Two different issues here.

"Browser asks me to activate Flash over and over again" is a much publicised browser issue. Browsers are slowly deprecating Flash. They are the last "annoy the users with constant reactivations" phase now. The last phase, at the end of this year, will be to discontinue Flash entirely. Nothing Plarium can do here. When that happens, Plarium Play will be the only way to access the game, as Plarium decided not to make HTML 5 versions of their games.

As for your loading problems, I don't have them, nor does anyone I'm talking to. It is safe to assume it may be an issue on your side (network, OS, browser, account,... impossible to say based only on your "the game is not loading"). The only way Plarium can help you is if you follow the steps in the first post here. Without a HAR file, devs have no way of seeing what is happening, and they have no chance of helping you.

You might want to try a different browser as a quick fix attempt. Chrome seems to work best for most players.
